What's missing, can't build with Qt SDK 1.1

[jkosonen]

I'm trying to get the environment up in a new machine. Can't remember all the steps I need to do before I get this working.

Now it says with S^1

process_begin: CreateProcess((null), arm-none-symbianelf-g++ -dumpversion, ...) failed.
process_begin: CreateProcess((null), arm-none-symbianelf-g++ -print-libgcc-file-name, ...) failed.

and with S^3

Warning: No HW compilers detected. Please install either GCCE or RVCT compiler to enable release builds.
Warning: No valid release platforms in SYMBIAN_PLATFORMS (WINSCW GCCE ARMV5 ARMV6)
Most likely required compiler(s) are not properly installed.

What are the missing pieces?

You don't need to do anything with a proper install. GCCE will be under [SDK]/Symbian/tools/gcce4/
Seem that somehow got deleted. Check your Qt Version and Toolchain in the global prefs and make sure they are set up properly.

I'm having the same problem. I found my gcce4 in C:\QtSDK\Symbian\tools\gcce4. How do I global prefs?

[lalalalalalalalala]

Oh, you go into QTCreator -> Tools -> Options -> Tool Chains.
The GCCE (4.4.1) and Symbian GCCE Toolchain are set up properly.
However, when I create a HelloWorld.C file in an empty directory:

#include <QApplication>
#include <QPushButton>

int main(int argc, char *argv[])
{
QApplication app(argc, argv);

QPushButton hello("Hello world!");
hello.resize(100, 30);

hello.show();
return app.exec();
}

Then go into cmd, then go to the qt project directory, then type in
setx EPOCROOT C:\QtSDK\Symbian\SDKs\Symbian3Qt474\epoc32 (only have to do this once; sets variable for future sessions)
qmake -project
qmake

I get:

Warning: No HW compilers detected. Please install either GCCE or RVCT compiler to enable release builds.
Warning: No valid release platforms in SYMBIAN_PLATFORMS (WINSCW GCCE ARMV5 ARMV6)
Most likely required compiler(s) are not properly installed.

What should I do? Please help.

Also, here is my Qt Versions screen. Looks pretty bad.



But the path is valid and qmake.exe is there!

I resolved that problem by uninstalling Qt, then manually deleting C:\QtSDK, then cleaning my registry with CCleaner, then downloading the full installer and installing it with the MinGW feature enabled, then adding C:\QtSDK\Desktop\Qt\4.8.0\mingw\bin to my PATH variable. Now I type
> qmake -project // no complaints, generates some files
> qmake // doesn't say anything
> make // the below results.
make -f Makefile.Debug

Looks like using QCreator instead of the command line solves all my problems. It would be nice if that was made clear on the windows installation page. Something like "Install our MinGW thing NO NO BAD IDEA DON'T DO IT USE QCREATOR INSTEAD" would be abundantly helpful.

EDIT: Another problem. Looks like the source code I got has errors.



EDIT: Solved! I uninstalled Qt SDK, removed all its files manually because there were leftovers, cleaned the registry with ccleaner, downloaded the offline installer, installed it using default settings, and used Qt Creator instead of the command line. Thanks for all the help, guys!
